Question

What is the magnitude of the magnetic field of a loop carrying constant current in the center of the loop?

Magnetic field field due to a loop of current r=(x+ + y 12 dBy Imagine a thin current loop of radius R as in the figure above carrying a constant current I in the direction out of the page (the loop in the figure is turned slightly for a better view). What is the magnitude of the magnetic field due to the loop at point P on its axis, a distance x from the center? Again express your answer in terms of parameters I, R, X, Y, N, MO B =
